Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

Aerosols have recently been defined as a serious atmospheric pollution problem in the Greater Athens Area (GAA). This research is mainly focused on assessing the PM10 concentration levels in the GAA atmosphere through simulations. The model results of the chemical constituents of PM10 are satisfactory comparing to measurements; the discrepancies are attributed to the re-suspended and seaborne ...

Forty elemental concentrations in different size particles were measured at a roadside site and a suburban site of Hong Kong using a ten-stage MOUDI impactor (Mode 110). Some elements (Cr, Fe, Co, Cu, As and Ba) have clear spatial variability, with ∼100% higher concentrations in roadside atmosphere than in suburban atmosphere, showing obviously vehicle-related sources for those elements. However, ...

ABSTRACT Coal mines are the major sources of suspended particulate matter. To implement any control techniques or to install any control equipment around the coal mines, ambient concentration of suspended particulate matter should be known. In this paper a model is developed to find the concentration of suspended particulate matter at various locations away from the source. The model is ...

Ambient particulate measurements were carried out using TE-PUF sampling and a Universal Air Sampler between 8 March and 25 April 2001 at Taichung. Samples were collected every 6 hours beginning at 0100 LST (Local Standard Time) each day at two sites, one at a university campus and the other at a roadside. Chemical species (Cl-, NO3-, ...

On 8th January 2012 a tiny ultra-light aircraft left Ljubljana in Slovenia on a mission to circumvent the globe using the smallest amount of fuel per distance flown whilst recording ambient levels of Black Carbon (BC) – one of the most important measures of air quality in terms of both human health and climate change. UK based particulate monitoring specialist Jim Mills from Air Monitors ...

Epidemiological studies have shown correlations between the concentration of particles in the air and increase of daily rates of respiratory and cardiovascular diseases and mortality (Douglas et al.,1992; Jonathan et al.,1995; Auron et al.,1995). Elevated lung cancer rates among women in rural china have been attributed to emissions from their coal-fired stoves (Mumford et al.,1987;Alder and ...

Understanding how the South Asian monsoon will change in response to global warming and resolving the uncertainties in projected changes are ‘demanding tasks’ for climate science, a review says. Current state-of-the-art general circulation models have difficulty simulating the regional ...

Exceedences of air quality limit values represent breaches of Community law which can have significant legal consequences for the Member States. For some existing limit values, such as those in directive 1999/30/EC (1st Daughter Directive), an exceedence which is caused by particular natural sources can be ignored for the purposes of ensuring compliance with Community law. For example, Article ...

Aerator/mixer system reduces effluent discharge BOD, TSS and phosphorus A goal of many communities in planning wastewater treatment facilities is to minimize the footprint, reducing land use. To reach this goal, a Chinese municipality built their oxidation ...

Sustainable development continues to filter down into the business world. In April, the British Stainless Steel Association held its first conference on the theme. Delegates heard that stainless steel may have a vital role in solving environmental problems in applications such as renewable energy projects and more fuel-efficient vehicles. But they were also told that regulatory and competitive ...

' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

The textile industry is plagued by air pollution problems which must be resolved. In particular, smoke and odor arising in the process require abatement. Air pollution control technology is available today which will serve the textile industry well into the 21st century. The nature of the problem The major air pollution problem in the textile industry occurs during the finishing stages, ...

Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...
